Fort Hill State Memorial [OH]
Fort Hill State Memorial is a nature preserve containing one of the best preserved Indian hilltop enclosures in North America. The Hopewell Indians (100 B.C.A.D. 500) constructed the 1 1/2 mile long earthwork hilltop enclosure as well as at least two ceremonial buildings and probably a village in the Brush Creek Valley.
The site is open to the public.
